England Academy centre Jacob Wardle will join brother Joe in the Huddersfield full-time squad for 2016.
Giants MD Richard Thewlis said: “Jacob has come through our Scholarship system at the Giants right from the start and it’s a credit to himself and his coaches that he emerged at the end of Scholarship age as probably the most sought after youngster in the game.
“I am delighted that he has remained a Giant and much of the credit for that goes to Andy Kelly and his team.
“The system here encourages elite Rugby League alongside education and it’s clear from my feedback that the parents of the younger players are very happy with our offering.
“In Jacob’s situation he has already trained at the back end of the year with the first grade squad and that situation will continue for him where practicable.
“He will be new into the Under 19 team next year alongside the signings we announced a few weeks back and his three-year term of contract gives him every opportunity to develop into a Super League player.”
